Spinal Cord Stimulation for Low Back Pain: A Systematic Review.

Abstract

Purpose of review: Chronic low back pain (LBP) is a prevalent and debilitating condition affecting millions worldwide. Among emerging interventions, spinal cord stimulation (SCS) has gained attention as a potential alternative for managing chronic LBP, particularly when alternative approaches fail to provide adequate relief.

Recent findings: This systematic review focuses on both residual pain levels and ability to perform daily tasks after treatment with SCS. The present investigation includes a systematic search for studies from PubMed, Google Scholar, and Cochrane, and Embase. Sources were eligible for inclusion in the review if they were published from 2010 to present (May 1, 2024). 8 studies involving a total of 1,172 patients were evaluated. This systematic review demonstrated that SCS is superior to conventional medical management (CMM) for both short and long-term pain relief, functionality, psychological well-being, and opioid dependency. Furthermore, newer SCS approaches, such as high frequency (HF), differential target multiplexed (DTM), and multiphase SCS all demonstrated improved efficacy over traditional SCS for pain relief and functionality scores. Adverse event rates for all trials were low and represent the safety of SCS treatments. The present investigation provides insight into the capabilities of both traditional SCS and HF SCS, DTM SCS, and multiphase SCS as compared to baseline pain and functionality as well as conventional medical management (CMM). This review grants physicians a broader picture of the applicability of SCS, its safety profile, and the opportunities it offers for pain reduction and functionality over CMM.
